Rush Limbaugh to ESPN.

For real. The radio talk show host will be on the Sunday NFL Countdown show, offering comments and observations.

Whatever else you think of Limbaugh (he's more listenable in the opposition than as a defender of government), he knows his football. He was also reportedly on the short list as a color commentator for MNF the year Dennis Miller was hired.

This could be very interesting:

Limbaugh, who will appear either on the show's Bristol, Conn., set or via satellite, will provide a weekly opinion piece on an aspect of the NFL making news that week, and participate in impromptu exchanges with the analysts and challenging their opinions on various issues. Limbaugh will be allotted three challenge opportunities to use at his discretion during the show.

It will be hit or miss. If it doesn't work, it won't survive the season. If it does, expect to see Limbaugh doing color work for MNF when Madden hangs it up.
